Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 108CKE025MLQ is determined by the following critical parameters:

Electrical Parameters:

• Capacitance: 1000 µF (exact match required)
• Voltage Rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 2000 Hrs @ 105°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Size / Dimension: 0.394" Dia (10.00mm) (exact match required)
• Height - Seated (Max): 0.689" (17.50mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria and are classified as parametric equivalents or direct manufacturer alternatives.

Engineering Selection Recommendations

108CKE025M (Cornell Dubilier / Illinois Capacitor)

This substitute is a parametric equivalent from the same manufacturer and series. It maintains identical electrical specifications including capacitance, voltage rating, tolerance, ESR, and lifetime rating. Mechanical dimensions and lead spacing are identical. Both parts are Active in product status and RoHS3 compliant. The primary difference is packaging format (Bulk versus the original specification). This part is suitable for direct substitution in applications where the original 108CKE025MLQ is specified.

25PX1000MEFC10X16 (Rubycon)

This substitute is a direct manufacturer alternative from Rubycon's PX series. It matches the critical electrical parameters: 1000 µF capacitance, 25 V voltage rating, ±20% tolerance, and 2000 Hrs @ 105°C lifetime. Mechanical dimensions, lead spacing, and mounting type are identical. The operating temperature range extends to -55°C (versus -40°C for the main part), providing broader temperature coverage. ESR is not specified for this part. Both parts are Active in product status and RoHS3 compliant. This part is suitable for direct substitution in applications where the original 108CKE025MLQ is specified.

Frequently Asked Questions (FAQ)

Q: Can 108CKE025M be used as a direct replacement for 108CKE025MLQ?

A: Yes. Both parts are from Cornell Dubilier / Illinois Capacitor's CKE series with identical electrical and mechanical specifications. The difference is packaging format. Both are Active products with RoHS3 compliance.

Q: What are the differences between 108CKE025MLQ and 25PX1000MEFC10X16?

A: Both parts share identical capacitance (1000 µF), voltage rating (25 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), and mechanical dimensions. The 25PX1000MEFC10X16 has an extended operating temperature range (-55°C to 105°C versus -40°C to 105°C). The ESR specification is provided for 108CKE025MLQ but not for the Rubycon part. Both are Active products with RoHS3 compliance.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed parts, including the main part 108CKE025MLQ and both substitutes, are through-hole mounted radial can capacitors with identical lead spacing of 0.197" (5.00mm).

Q: Do all parts meet RoHS3 compliance?

A: Yes. The main part 108CKE025MLQ and both substitute parts (108CKE025M and 25PX1000MEFC10X16) are RoHS3 compliant.

Q: What is the significance of the ±20% tolerance specification?

A: The ±20% tolerance indicates the allowable deviation from the nominal 1000 µF capacitance value. All listed parts share this tolerance specification, ensuring consistent performance characteristics across substitutions.

Q: Can the 25PX1000MEFC10X16 be used in applications requiring the full -40°C to 105°C operating range?

A: Yes. The 25PX1000MEFC10X16 operates across -55°C to 105°C, which encompasses the -40°C to 105°C range of the original part. The extended lower temperature limit provides additional operational margin.

Q: Are there inventory considerations when selecting a substitute?

A: Inventory levels differ among the parts. The main part 108CKE025MLQ has 870 pieces in stock, while 108CKE025M has 5288 pieces and 25PX1000MEFC10X16 has 10100 pieces available. Selection may depend on project timeline and quantity requirements.
